Influence of the intermediate sowings of fodder crops on the agrophysical indicators of the irrigated soils in Azerbaijan dry subtropics

The findings of the studies on the influence of intermediate crops' sowings in double or triple harvests fields system on the agrophysical indicators of Irragri Gipsic calcisols and Irragri Kastanozems in dry subtropics of Azerbaijan are presented. The optimum variant that provides the greatest supply of plant residues to the soil (18.50 and 19.69 t/ha) and the improvement of agrophysical indicators of the studied soils— decrease of bulk density, improvement of particle density, increase of total porosity and water permeability, increase of the coefficient of structural properties in comparison with other variants, and also enhancement of the food potential in this part of the republic—was established.
